ALONZO L. NICHOLSON, OF ROCKWELL CITY, IOWA.

WRENCH AND CLAMP COMBINED.

SPECIFICATION forming part of Letters Patent No. 755,578, dated March 22, 1904.

Application filed April 23, 1903- Serial No. 154,033. (No model.)

To all whom it may concern:

Be it known-that I, ALoNzo L. NICHOLSON, a citizen of the United States, residing at Rockwell Oity,in the county of Calhoun and State of Iowa, have invented a new and useful Wrench and Clamp Combined, of which the following is a specification.

My object is to facilitate taking off and putting on a carriage-wheel as required for applying a lubricant to the axle; and my invention consists in a wrench adapted to be applied to a nut and a clamp combined therewith as required to fasten the wrench to the hub so that the nut can be turned on and off and is constructed as hereinafter set forth, pointed out in my claim, and illustrated in the accompanying drawings, in which Figure 1 is a perspective view of the wrench getached from hub-clamping jaws and hanles. members of the clamp. Fig. 8 is a perspective View that shows the wrench, the clamp, and a handle combined as required for practical use. Fig. 4 is adetail view, partly in section, and shows the manner of connecting all the parts by means of a screw-bolt and nut.

The numerals 10 and 12 designate the jaws of the wrench, rigidly connected by a crosspiece 13, and a loop 14: is rigidly connected with the under side of the cross-piece by casting in a mold or in any suitable way. The

- cross-piece 13 and loop 14s are provided with coinciding perforations for the passage of a screw-bolt. Elbow-shaped clamp-irons 15 and 16 are provided with longitudinal slots 17 and adapted to be adjustably retained in the loop 14 by extending them through the loop from its opposite sides and then passing a screwbolt 18 down through the coinciding apertures in the cross-bar 13 and the loop 14: and securing them by placing a handle 19 on the screwbolt and a nut 20 on the end of the bolt, as clearly shown in Fig. 4, so that the overlying parts of the clamp-irons can be fastened together by means of the bolt and nut.

A screw on the end of a handle 22 is seated Fig. 2 is a perspective view of two of the in the jaw portion of the clamp-iron 15. and when the jaws of the slidable clamp-irons l5 and 16 are placed inside the hub-band of a wheel the jaws 10 and 12 will be in engagement with a nut on the end of the axle. By then operating the screw 21 the clamp-irons 15 and 16 will be spread apart to engage and fasten to the inside of the hub-band as required to fasten the complete device to the wheel. By then turning the wheel the nut on the axle will be freed therefrom as required to allow the wheel to be taken ofi to lubricate the axle, and by replacing the wheel and nut carried in the jaws 10 and 12 and turning the wheel in a reverse way the nut will be re placed on the axle without touching the nut by the fingers. By operating the screw 21 the complete device can be readily loosened and removed from the wheel.

Having thus described the purpose of my invention, its construction, application, and operation, the practical utility thereof will be obvious to persons familiar with the art to which it pertains, and

What I claim as new, and desire to secure by Letters Patent, is

A nut-wrench and clamp combined, comprising two jaws rigidly connected by a crosspiece having an aperture at its center and a loop below the cross-piece having an aperture at its center, two elbow-shaped clamp-irons, each having a longitudinal slot in its end portion, a handle having a longitudinal bore, a screw-bolt extended through the coinciding apertures in the cross-piece that connects the wrench-jaws and the aperture in the loop and also through the slots in the clamp-iron, a nut on the end of screw having an integral handlebolt and a screw seated in one of the clampirons, combined to operate in the manner set.

forth for the purposes stated. ALONZO L. NICHOLSON.
